Patent attributes
A utility compactor is disclosed that includes a roller disposed on top of and connected to a base plate. The roller has two opposing vertical supports. The compactor also includes an eccentric vibratory shaft extending between and rotatably connected to the two vertical supports of the roller. The eccentric vibratory shaft includes a first rotor shaft coaxially spaced apart from a second rotor shaft. The first and second rotor shafts are coupled together by an offset shaft. The offset shaft has an I-beam cross section and includes a first angled portion, a second angled portion and a center portion disposed between and coupling the first and second angled portions together. The first angled portion is coupled to the first rotor shaft; the second angled portion is coupled to the second rotor shaft. The first and second angled portions are angled with respect to a first axis passing through the first and second rotor shafts such that the center portion has a second axis that is offset from and at least substantially parallel to the first axis.
